lGAS-IRON.

Application led February 13, 1909.

T o all whom it may concern:

Be it known that l, HOWARD E. LUCAS, a citizen of the United States,residing at Massillon, in the county of Stark and State of Ohio, haveinvented a new and useful lmprovement in Gas-Irons, of which thefollowing is a specification.

rfhe invention relates to a smoothing iron adapted to be heated by a gasflame burning within the body of the iron; and the 0bjects of theimprovement are to provide a simple form of valve and mixer forcontrolling and admitting the supply of gas and air to the burner, andto provide flanges in the iron for shielding the flame and deliect ingit downward to impinge and heat the bottom of the iron.

The primary objects of the improvement, thus set forth in general terms,and other benefits and advantages, are attained by the construction andarrangement of a preferred embodiment of the invention, illustrated inthe accompanying drawings, forming part hereof, in which- Figure 1 is alongitudinal section in the median vertical plane of the iron, showingthe valve and mixer attached thereto; Fig. 2, a horizontal section online 2#2, Figs. 1 and 3; and Fig. 3, a rear end elevation of the iron onone side and a cross section on line 3 3, Figs. l and 2, on the otherside, without the valve.

Similar numerals refer to similar parts throughout the drawings.

The principal parts of the iron include the hollow body 1, the cover 2,the handle 3, the burner 4t, the mixer 5, the valve case 6 and the valvestem 7.

The cone-shaped valve seat 8 is formed in the valve case in which thecorrespondingly cone-shaped valve proper 9 formed on the forward end ofthe stem is adapted to lit, and the stem is arranged to screw inland outof the case to seat and unseat the valve. The axial gas port 10 isprovided in the case and extends from the apex of the seat cavity to thefree end of the valve in the mixer.

The gas inlet pipe 11 is formed or attached on one side of the case andis preferably inclined rearward at an angle of about Ll5 degreesthereto, to the rea-r end of which pipe a suitable flexible supply tube(not shown) is adapted to be joined. The gas inlet pipe opens into oneside of the cone-shaped seat Specification of Letters Patent.

cavity, so that a very slight movement of the valve proper to and fromits seat serves to open, regulate or close the valve; and it is notnecessary to reduce the size of the stem proper of the valve to make away for the gas.

The mixer 5 is shaped as a bell and is secured to the rear end of theiron body by means of the flanges l2 and the screws 13. rl`he larger endof the bell is directed to the rear and the open frame or spider la isformed or attached therein, which spider includes the axial bearing 15into which the forward end of the valve is adapted to be screwed. Theforward smaller end of the mixer is continuous with the rear end of theburner l which latter is screwed into the aperture 16 formed in the rearwall of the iron body.

The burner 4l is preferably made in the form of a tube, the free end ofwhich extends well forward in the cavity of the iron body and is closedby meansof the plug 17. The transverse slots 1S are provided in thelower side of the burner through which the mixed gas and air are adaptedto flow for burning in the iron cavity. lt is evident that by reason ofthe bell-shaped form of the mixer, a sufficient amount of air isadmitted through its larger rear end to mix with the gas to causecomplete combustion.

The depending flanges 19 are formed or attached on the iron cover, andthese flanges are preferably located parallel with the side walls of theiron body and extend downward on each side of the burner and forwardfrom the rear wall to a junction near the forward end of the iron, thusforming a complete shield around the burner excepting only on the underside, and leaving a comparatively narrow interval between the flangesand the side and forward walls of the iron body. The openings or vents2O are provided in the upper portions of the side and forward walls ofthe iron through which the products of combustion are adapted to escape.

t is evident that the depending flanges will shield the flame from anyundesirable air currents which might be blown or sucked in through theexit openings; and that the flame from the burner will first fiowdownward to impinge the bottom of the iron, thence laterally and forwardunderneath the edges of the flanges to impinge the side and forwardwalls of the iron, and thence upward in the interval between said wallsand the flanges to an outlet through the openings in the upper portionsof said walls. It is furthermore evident that by reason of the tortuouscourse which the flame must follow from the burner to the exits, thecombustion will have been fully completed, and that no live flame willever issue from the vents.

The under side of the cover and the inner side of the rear wall betweenthe flanges and the inner sides of the flanges, which parts form whatmay be called a combustion chamber, are preferably lined with asbestos2l to prevent the radiation of heat through these walls,therebyinsuring` that substantially all the heat caused by the combustion ofthe gas will be deflected downward to impinge the bottom of the iron.

What I claim as my invention, and desire to secure by Letters Patent,is`

l. A smoothing iron having a hollow body with a gas burner therein andhaving openings in the upper portions of its walls, and flangesdepending from the cover on each side of the burner and arranged toshield the:

flame from the openings and to deflect the flame first downward toimpinge the bottom and thence upward between the walls and the flangestoward the openings.

2. A smoothing iron having a hollow body with a gas burner ings in theupper portions of its walls, vand flanges depending from the cover oneach side of the burner and arranged to shield the vflame from theopenings and to deflect the flame first downward to impinge the bottomand thence upward toward the flanges and the openings, the combustionchamber formed by the flanges being lined with asbestos to prevent aradiation of heat therefrom.
